Seasonal Lasagna with Butternut Squash and Spinach, layered with marinara sauce makes an excellent vegetarian main for Thanksgiving or just any dinner.
The first time I made a butternut squash lasagna, it was with a creamy white sauce and however delicious it was, it did not work well as a vegetarian main for me. It was a tad too sweet and uni- dimensional in taste that I could eat only very little of it.
That is when I came across this recipe for a butternut squash lasagna with a marinara sauce. When I read it at first, I wasn’t sure how this could work. I however did try this one Thanksgiving and loved it!
This has been my go-to vegetarian main recipe for the last few Thanksgiving dinners. We always host Thanksgiving at our place and I make a roasted chicken or a cornish hen for everyone else. I am a vegetarian and I love to make a little something special as a vegetarian main as well.
I personally love to make this lasagna as it is very seasonal with the butternut squash as the main ingredient and the marinara sauce balances the sweetness of the squash very well. I think this will continue as my vegetarian main for many more Thanksgiving dinners to come.
We love this lasagna recipe because:
- It is super delicious as it is made from scratch.
- This is a vegetarian lasagna recipe
- It is bursting with flavors from the butternut squash and spinach
- It can be made ahead or even frozen.
